[Effect of idea]

As described above, in the present invention, a locking protrusion is made to protrude upward from the indoor side end of the upper end of the circumferential edge, and an elastic contact piece is extended from the lower end of the circumferential edge toward the wall side, and this elastic A bent piece that protrudes upward is provided at the tip of the contact piece, and the bent piece is attached to the upper end of the corner edge, whose vertical cross-sectional shape is approximately equal to the cross-sectional shape of the vertical surface of the edge, toward the wall. At the same time, a locking piece is extended upward on the wall side at the lower end of the corner edge, and the back surface of one side end of the corner edge is overlapped with the front side of one side edge of the corner edge. The bent bending piece is fitted to the locking protrusion at the upper end, and the locking piece is fitted to the bent piece at the tip of the elastic contact piece at the lower end of the circumferential edge, and the elastic force of the elastic contact piece presses the locking piece against the wall. Since the corner edges are held on the edges by these locks, the corner edges can be attached without the need for special members such as edge supports to fix the corner edges. In addition, the vertical cross-sectional shape of the corner edge is formed to be approximately equal to the cross-sectional shape of the vertical surface of the corner edge, and one side of the corner edge is formed on the front side of one end of the corner edge. Since the back surfaces of the side edges are overlapped, the circumferential edge and the corner edge can be closely connected, and the elastic contact piece at the lower end of the circumferential edge can be connected to the bent piece at the tip. Since the locking piece is locked and pressed against the wall by the elastic force of the elastic contact piece, the locking piece is locked on the outside of the elastic contact piece at the corner part, and the elastic force of the elastic contact piece presses the locking piece against the wall. By applying an outward pressing force, the locking piece is pressed against the wall, thereby eliminating rattling and making it possible to maintain watertightness.
